While I said this is kind of like roleplaying with tossing around these ideas, you don't have to do a whole spiel about how your observed the idea from the volunteer(technically there are no volunteers they are just your ideas). For example:

"I was looking the screen attached to Cherry Top's machine when this great idea popped up!"

The statement above isn't required for all your ideas (however if you want to feel free to do so). By making a statement in the forum concerning an idea it will be automatically assumed by your fellow Observers that you observed it.

Now as an Observer you mention ideas that your volunteer comes up with in their long... long... long slumber. So don't copy the ideas mentioned by other Observers.

Feel free to discuss the observations made by other Observers.

Also be nice to the volunteers you look over. Pulling pranks on them and such is kind of mean and pointless (considering that they won't be waking up for a long... long... long time).
